Abstract: An apparatus for use in maintaining a desired orientation of an implement is provided. The apparatus includes orientation sensing equipment operable to sense the orientation of the implement, and an orientation indicator operable to be mounted relative to the implement, the orientation indicator having a plurality of indication portions, and when the orientation indicator is mounted relative to the implement, the indication portions are positioned so as to be visible from different locations around the implement. In use, when the orientation of the implement deviates from the desired orientation, one or more indication portions provide a visible indication of a direction in which the implement has deviated from the desired orientation.

Abstract: An apparatus for indicating temperature of a liquid inside a bottle includes a housing having an upper surface configured to support a bottle and a base surface configured to rest on a structure. The apparatus further includes a non-contact thermometer located inside the housing and one or more indicators to display or provide an indication of a temperature state of the bottle. The apparatus also includes a processor. The non-contact thermometer senses temperature of a bottle placed on the upper surface of the housing and sends signals relating to the temperature to the processor, wherein the processor is configured to alert a user if there is an increase in temperature state of the bottle.

Abstract: A transmission device including a body, an input member extending along the body, and having a rotational axis, a gear assembly connected to the input member, having an inner gear, one or more intermediate gears engaged with the inner gear; and an outer gear engaged with one or more intermediate gears, wherein in a first position the gear assembly is configured to rotate at substantially the same rate as the input member and axial movement of at least one component to a second position, in a direction substantially parallel to the axis of rotation, allows the gear assembly to provide to an output member a different output rate relative to the input member, and an actuator movable between a first position at which the gear assembly moves to its first position and a second position at which the gear assembly moves to its second position, the actuator moves under hydraulic pressure.

Abstract: A method of simulating the time taken to perform a weather restricted marine operation comprising creating a marine operation model, inputting one or more variables to the model, running the model in accordance with the one or more variables, the model determining the time taken for performing the operation.

Abstract: Two bone sawing blades are attached in a spaced parallel alignment and attached to a handle for cutting out a section of a pelvic bone in field dressing a game animal. A pivoting handle with a side opening enables the double blades to be pivoted into the handle for storage. A rigid handle is attached to the blades by a hand shield.

Abstract: A handgrip handle connects to an elongated protective paddle blade with an elongated trough along the length of the paddle blade and an end stop at each end of the trough. The trough receives a gutting blade when gutting a game animal to prevent puncturing the organs. The trough alternately receives a pelvic bone cutting saw when sawing the pelvic bone for removing game animal internal organs to guide the saw blade and prevent puncturing the organs. The handle may be pivotally attached to the paddle blade. A pivotable gut blade may be attached to the pivotable handle.

Abstract: A method of modelling the effect of a fault on the behaviour of a system. The method comprises modifying a functional model of a system to specify a fault in the system; running the model in accordance with a test, the test having an input and an expected output, the input defining the value of a least one input variable over a period of time and the expected output defining the expected value of at least one output variable over the period of time; the functional model calculating, in dependence on the value of the input variable defined by the input, a modelled output comprising the modelled value of the output variable over the period of time; and comparing the modelled output with the expected output to determine a severity score for the fault based on the difference between the modelled output and the expected output.

Abstract: A physiological sensing stethoscope suitable for use in high-noise environments is disclosed. The stethoscope is designed to be substantially matched to the mechanical impedance of monitored physiological activity and substantially mismatched to the mechanical impedance of air-coupled acoustic activity. One embodiment of the stethoscope utilizes a passive acoustic system. Another embodiment utilizes an active Doppler system. The passive and active systems can be combined in one stethoscope enabling switching from a passive mode to an active mode suitable for use in very high-noise environments. The stethoscope is suitable for use in environments having an ambient background noise of 100 dBA and higher. The passive includes a head having a housing, a flexural disc mounted with the housing, and an electromechanical stack positioned between the housing and the flexural disc in contact with the skin of a patient. The active system detects Doppler shifts using a high-frequency transmitter and receiver.
